Used VeQtr first time at Auto X today. My flight recording trigger is set to 10 mph. I noticed that the initial frames of the video don't start until I hit 10 mph. I am at 0 mph for at least 20 sec before take off. An ideas why the initial video frames are not from launch? Any suggestions help. I can always default to a screen tap as I get staged at the starting line but that is just one more thing to think about.

Second day. I tried to use the screen tap. Problem was our staging was too long, so the system would sense that I was stopped, stop recording and then I could not get it start recording in time before launch. I just lived with the missing frames.

You can use the CaptureBufferDuration registry value to adjust the video precapture buffer length. Run regedit, find HKEY_CURRENT_USER\Software\MaxQData\CameraCaptureSetup and create a DWORD value named CaptureBufferDuration if it doesn't already exist. The value is the number of seconds of video pretrigger capture before the FRT triggers; the default value (if this value is not present) is 2. Most cars can reach 20 MPH in under 2 seconds, but if you are still consistently not getting the beginning of your run, you can try changing this value to something like 5.

I have not tried it yet but it makes sense. I will post this weekend after some experimentation.

Did you ever do some testing with these settings Chris? Our setup is missing the first few seconds of the run. It seems more like its not using a buffer at all vs. it being too small. I know I'm hitting 20mph in 2 seconds, but the video seems to be starting the instant I hit 20mph, and recording nothing before that point._________________project:BDR

Increasing the buffer worked a little better....the video starts just after launch. I had a co-driver last weekend who was new to Auto X so he launches were slower. It took her longer to get to 20 mph so the video started slightly later in the run.

Audio was better with v3.3a. I forgot to use the new codec settings so I can't tell if that will have any affect. I am using an external lapel mic, both web cam mics are disabled in Control Panel and the Web Cam SW. I need to find the correct gain setting for the mic SW driver.

search YouTube for wrxSTiautoxer to see video from last week Cumberland, MD Autocross. Buffer not changed for 8/14. On 8/15 and 16 it was.

I never did get it figured out last season. We have a test and tune in 2 weeks. I'll mess with settings then. I am considering a newer system with faster PC. Last year if I did not have enough time between runs, the Morgan Codec took too long to render and I was launching before Flight was ready again,

I have the aforementioned registry thing set to 5. Also, I reduced the recording start threshold to 11 mph. I now capture a couple seconds prior to launch pretty reliably. The trick is to not go fast enough in paddock/queue to set the recording trigger, so it starts and stops.

Make sure also that under camera capture settings (in setting app), and then under output file settings, that "enable precapture buffer" is also checked. I this works with the registry setting of 5 to cache 5 seconds of video.

Now if I can just get rid of that static noise thing...
